I can now say I have an 83+, an 84+, and a fx CG-10
EDIT: and I think there is already another thread for this -- I thought you had posted this in the other one
I think that
Another Batch of Calcs might have been an appropriate thread to use for this, but oh well, close enough. I'll have to take a picture of my current twenty-calculator collection here, plus there are the other fifteen that are indefinitely AWoL.

My 84+SE meets my Prizm for the first time! (And I met my Prizm for the first time, too
)

Haha, very nice. Too bad that you have an 84+SE instead of an 83+/SE; you can't use your Prizm link cable to link with the TI-84+/SE series because of the inset link port.

Yet, sure, but I have no doubt that that will swiftly change once the methods to access the link port of the Prizm are found.

To hijack the thread a bit...what's the problem with this? Electrical differences, or is it purely a lack of understanding of the Prizm's link protocol? I would think we could easily whip something up TI-side.

I'm thinking more from the perspective of being able to send and receive files from it (or whatever is possible with the built-in functionality). I see that as something we can accomplish now TI-side, where the other stuff will come with time.

Yes, that would be possible if we know how the protocol works. It's pretty much the same as on previous Casio calcs.
So the problem is purely software? Something we could monitor and/or reverse-engineer? Is there any public documentation on this?

Purely software indeed. Both calculators use 2.5mm stereo link cables with TTL-level signalling. There is no protocol documentation that I know of, but there are some more knowledgeable Casio programmers who repeatedly evade me.

Yes. There's a small hardware problem (some Casio cables don't fit in some TI devices), but that problem isn't something that hinders us.

Not that I know of.
Regarding the first point, of course you can just use TI link cables instead. Do we know of any documentation on the 9860's link protocol, or other Casio calculators?

I haven't found any. It's likely that most people don't care about stuff that's as low-level as the link port, since most people are using C.

Seems like something a custom link cable could fix.
Nice, I am jealous, all I have is 1 ti-84+ and 1ti-84+se.

or use a mini-usb to mini-usb connector 
Knowing the Prizm it may be mapped to a GPIO pin of some sort, which would make things exceedingly simple, if its more complex than that well have to do some digging.
